Additives for animal feed

Abstract

The present invention relates to the combination of organic acid salts with at least one active ingredient of plant origin, preferably essential oils, partially protected with vegetable fats and/or oils, which prevent these active ingredients from being digested by stomach enzymes during the digestive process. The sodium salts of short-chain acids, preferably salts of butyric, acid are preferred. The preferred essential oils are ginger, piperine, oregano, garlic, thymol, carvacrol, cinnamaldehyde and/or any combinations thereof. The combination of organic acid salts and the essential oils protected with vegetable fats and/or oils, are used as powerful promoters or stimulants for animal growth, as organic bactericides against pathogenic bacteria present in said animals and as modulators of immune response thereof.

The invention claimed is: 
     
       1. A method for promoting animal growth comprising administering an additive to an animal, wherein said additive comprises a combination of sodium butyrate with essential oils consisting of essential oils of ginger and essential oil piperine, wherein the combination is partially coated with a palm stearin coating. 
     
     
       2. The method according to  claim 1 , wherein the sodium butyrate is in a proportion of 30-70% of the wet weight of the additive. 
     
     
       3. The method according to  claim 1 , wherein the sodium butyrate is in a proportion of 60% of the wet weight of the additive. 
     
     
       4. The method according to  claim 1 , wherein the essential oils consisting of essential oils of ginger and essential oil piperine are in a concentration of between 1-20% of the wet weight of the additive. 
     
     
       5. The method according to  claim 1 , wherein the essential oils consisting of essential oils of ginger and essential oil piperine are in a concentration of 10% of the wet weight of the additive. 
     
     
       6. The method according to  claim 5 , wherein the concentration of the essential oils of ginger is 5% wet weight of the additive and the concentration of the essential oil piperine is 5% wet weight of the additive. 
     
     
       7. The method according to  claim 1 , wherein the palm stearin coating is between 30-60% wet weight of the additive. 
     
     
       8. The method according to  claim 1 , wherein the palm stearin coating is 30% wet weight of the additive. 
     
     
       9. The method according to  claim 1 , wherein the concentration of sodium butyrate is 60% of the wet weight of the additive, the concentration of the essential oils consisting of essential oils of ginger and the essential oil piperine are 10% of the wet weight of the additive, and wherein the concentration of the palm stearin coating is 30% of the wet weight of the additive. 
     
     
       10. The method according to  claim 9 , wherein the concentration of the essential oils of ginger is 5% of the wet weight of the additive and the concentration of the essential oil piperine is 5% of the wet weight of the additive. 
     
     
       11. The method of  claim 1 , wherein the animal is selected from the group consisting of a chicken, a rabbit, and a pig.
